I am submitting soon and seek your assistance

Welcome @Beni_saint_joss_MBEMBA

I have paid a €100 deposit on €7,100 for my tuition fees (so I still have €6,100 to pay)

How do you plan to pay the remaining €6,100 of your tuition fees?

In summary, my question is whether I still need a guarantor or guarantors?

The AVI covers your living expenses, but you need to justify how you plan to finance the tuition fees. A sponsorship is an option.

Best regards!
